Joshua Harlow a96f49b9a5 Ensure the cachedproperty creation/setting is thread-safe ...

When the cachedproperty descriptor is attached to an object
that needs to be only created/set by one thread at a time we
should ensure that this is done safely by using a lock to
prevent multiple threads from creating and assigning the
associated attribute.

Fixes bug 1366156
